The Inbox that builds your network
Your tracks. Real connections. More ways to earn.
Inbox: The demo and promo system for electronic music professionals
Send demos and promos to the right people. Bring incoming tracks into one place to listen, organise and reply.

Make connections. Build sustainable income.
The DJ who plays your track. The label that starts a conversation. The producer who asks for your feedback. The listener who buys a release and comes back for the next one. These are relationships you can keep building on.
Some lead to opportunities. Some become collaborations or sales. All begin with an exchange worth making. Trackstack helps you keep the tracks, conversation and relationship connected, so you can choose what happens next.
Your tracks, skills and relationships are the foundations. We’re building Trackstack to help you turn that work into a life in electronic music, with more control over what comes next.
What DJs, producers and labels say
“Inbox means I can listen to every demo and promo fast during my busy schedule. Getting back to artists is important to me and Flow Inbox makes this easy and reliable.”
Jamie JonesDJ, Producer, Label Owner“I can give feedback to every single song. Everyone will know definitely whether the song is being listened to or not. It’s just a much better process.”
Patrick ToppingDJ, Producer, Label Owner“I have had music signed and great feedback from top artists through the use of Inbox. It simplifies what seems like a complex world into a few clicks.”
Tim TaylorDJ, Producer“While it usually took me days to go through demos and promos, I can now go through everything and keep my tracks organised within a few hours.”
DetlefDJ, Producer, Label Owner“It’s transformed how our team runs the label. Collaboration is smoother, and our communication with artists has never been better. Feedback and responses are more transparent and timely.”
Dan CostelloDJ, Producer, Label Owner“Being able to track if your promos are being downloaded or supported is incredibly helpful. It’s led to getting a number of tracks signed and some massive DJ support.”
DJ SKTDJ, Producer“Before Trackstack, I never knew if anyone was actually listening. Now, I can see exactly when DJs, artists, and labels check out my tracks. I’ve landed major releases on respected labels that once felt out of reach.”
CharlesworthDJ, Producer“Trackstack inbox is not only about ease, but about finding new artists who I haven’t heard of before and connecting with people who maybe don’t have the outlets their music deserves.”
KodewerkDJ, Producer“Before, we were juggling emails and a Trello board just to stay on top of submissions. Since switching to Trackstack, everything is finally in one place: submissions, feedback, internal notes, and decision-making.”
